Description

A kind of electric bakelite carrying roller and manufacture method thereof
Technical field
The present invention relates to the carrying roller that a kind of conveyor belts is used, definitely saying so relates to a kind of electric bakelite carrying roller and manufacture method thereof.
Background technology
The used carrying rollers of enterprise's transport plane belt conveyor such as existing mine, metallurgy, chemical industry are iron carrying roller or magnetic carrying roller.This carrying roller leak tightness is relatively poor, and easily evaporation is with mobile for its lubricant, and to making bearing easy to wear, service life is short; This carrying roller cooperates with belt conveyor, in use can produce electrostatic effect and the adhesion material, the wearing and tearing belt conveyor; The iron carrying roller is acid-alkali-corrosive-resisting not, and the magnetic carrying roller is fragile, and these two kinds of carrying roller weight are heavier, and transportation is very inconvenient with installation.
Summary of the invention
The objective of the invention is to: the problem that exists at existing carrying roller, for enterprise provide a kind of wear-resistant, good seal, no electrostatic effect, withstanding corrosion, in light weight, make things convenient for transportation and installation, the electric bakelite carrying roller of long service life and the manufacture method of this carrying roller.
The objective of the invention is to realize: a kind of electric bakelite carrying roller by the enforcement following technical proposals, include outer tube, be installed in the bearing seat at its two ends, dress is inserted in the locational rotating shaft of two end axles bearing central axis, be sleeved on bearing seat and change interaxle inside ball bearing and outer side seal, and be positioned at the jump ring assembly of they being kept apart, being stuck in the rotating shaft between the two and form, it is characterized in that: outer tube and two end axles bearing are the assembly of electric bakelite material manufacture.
Additional technical feature is: 1. being sleeved on bearing seat is the labyrinth type combination sealing with changeing interaxle outer gland sealing.2. described labyrinth type combination sealing is made up of two seal ring assemblies, and the vertical profile half section of a seal ring is shaped as shape, and the vertical profile half section of another piece is shaped as shape, the tortuous enclosure space gap dressing lubricating oil that they form in the middle of interting each other.3. described outer tube and two end axles bearing are the electric bakelite material, and the Main Ingredients and Appearance that is meant this material is glass fabric and the gluing that is mixed and made into by epoxy resin and phenol resin.4. make the method for electric bakelite carrying roller, include the gluing preparation, the glass fabric gluing, roll pipe, mould molding, demoulding cooling, machine up and all operations of assembling, it is characterized in that: the gluing burden process is meant that the epoxy resin with total glue weight 60-80% is mixed in the phenol resin of 40-20%, by steam hybrid resin is heated while stirring with 80 ℃-120 ℃, an amount of toluene and triethanolamine reinject, add thermal agitation cloth and be no less than 4 hours, hybrid resin becomes transparent adhesive tape.5. described glass fabric coating process is meant: with the hybrid resin transparent adhesive tape for preparing, be contained in the gluing machine glass fabric upper and lower faces gluing, glass fabric while move, gluing machine is to its gluing, on one side with 60 ℃-90 ℃ steam sized glass fibre cloth is dried.6. the described pipe operation that rolls is meant: with the glass fabric that double spread has been dried, be placed on and roll into pipe on the rotary machine.7. described mould molding and demoulding refrigerating work procedure are meant: with the pipe that the rolls into mould of packing into, the heating certain hour makes its moulding under 150 ℃ of-170 ℃ of temperature, be cooled to 120 ℃ of-130 ℃ of demouldings then, behind natural cooling, become electric bakelite pipe or bearing seat stock.8. described machine up operation is meant: electric bakelite pipe and electric bakelite bearing stock with making are machined to the corresponding assembly of carrying roller by designing requirement, and are mounted to the electric bakelite carrying roller.The invention has the advantages that: l) because carrying roller uses electric bakelite material of the present invention, in use do not produce electrostatic effect, sizing not, wearing and tearing have been reduced to belt conveyor, and improved the wear resisting property of self greatly, make big leap ahead in service life of carrying roller, experiment shows it is 4 times of iron carrying roller service life, is 7 times of magnetic carrying roller service life.2) electric bakelite carrying roller of the present invention has acid-fast alkali-proof erosion resisting advantageous property, and is not fragile.3) electric bakelite carrying roller of the present invention, its electric bakelite assembly has good heat-blocking action, and the evaporation of minimizing lubricant and mobile has reduced the wearing and tearing to bearing, has improved lubricant effect greatly.4) adopt the labyrinth type double containment between rotating shaft of the present invention and bearing seat, inner seal ring rotates with bearing, and exterior seal ring maintains static, and can prevent dust intrusion protection bearing.5) electric bakelite carrying roller of the present invention in light weight, be not afraid of and beat, be convenient to transportation and install.
